Simplify 15^c3

15^c3 cannot be simplified any further without knowing the value of c3. It is already in its simplest form.

To simplify 15^c3, we can start by expanding it using the exponent rule. The exponent rule states that for any positive real number a and integers m and n, (a^m)^n = a^(m * n). Applying this rule, we have:

15^c3 = (15^c)^3

Next, we can simplify the expression 15^c by applying the power rule. The power rule states that for any positive real numbers a and b, and any real number c, (a^b)^c = a^(b * c). Applying this rule, we have:

(15^c)^3 = 15^(c * 3)

Simplifying further, we have:

15^c3 = 15^(3c)

Therefore, the simplified form of 15^c3 is 15^(3c).
